If you're working with a Sony A7s (or similar) camera body perhaps you've already tried adapting Canon or other lenses which typically offer slow autofocus and at times clunky communication. Here's a short sample I did using the Sony A7s with a Samyang lens and a few Canon lenses shot in S-Log at 4K on the Atomos Shogun. Although it's possible to use Canon Lenses with a Metabones adapter, it's been buggy and of course slower autofocus than using a native Sony lens.

If you want better image stabilization, faster autofocus, and full support of lens communication, then maybe it's just better to stick with native Sony Lenses. I'm pretty set on going this route myself. Here's a list of new Full Frame FE Mount Lenses that I think would make for a perfect addition to your A7s. There's also two adapters that can be used as a Wide Angle or Fisheye Conversion on the 28mm Lens.

I tried the sony 24-70 and 70-200 and unfortunately they were unusable for wedding style shooting (video) Unlike the canon lenses the sony uses electronic focus and it was nearly impossible for me to pull focus on a moving subject

I've had some pretty good luck using a 24-105L Canon lens on my A7s with the Metabones IV for video. At first I was having connection / communication issues, but after the recent Metabones firmware update it has been working well.

Not sure what others are planning, but I picked up a Sony 55mm 1.8 E mount so I had at least 1 native lens, but plan to keep using my Canon glass. So far so good.
